About FCRL3
This gene encodes a member of the immunoglobulin receptor superfamily and is one of several Fc receptor-like glycoproteins clustered on the long arm of chromosome 1. The encoded protein contains immunoreceptor-tyrosine activation motifs and immunoreceptor-tyrosine inhibitory motifs in its cytoplasmic domain and may play a role in regulation of the immune system. Mutations in this gene have been associated with rheumatoid arthritis, autoimmune thyroid disease, and systemic lupus erythematosus. Alternative splicing results in multiple transcript variants.

About Brilliant Ultraviolet 661
Brilliant™ UltraViolet 661 (BUV661) is a red-emitting tandem fluorophore that combines BD Horizon® BUV395 and an acceptor dye. It can be excited by the 355 nm ultraViolet laser and collected using a 670/25 bandpass filter. BUV661 has an excitation peak at 498 nm and an emission peak at 657 nm BUV661 has a medium/high relative brightness, and is most commonly used for multicolor flow cytometry. This dye is part of the Brilliant™ UltraViolet dye family, developed and sold by BD Biosciences. This family of dyes uses BUV396 as the donor so that all dyes in the family can be excited by the 355 nm ultraViolet laser. Depending on the acceptor, the dyes in this family have different relative brightness ratings.
